In recent months, there were lots of offers for various Hitachi hard drives at very low prices.

I think, having purchased a total of six Hitachi hard drives, I know why: they are simply not reliable and Hitachi's policies re very suspect.

I purchased four of their 750 GB USB portable drives and two failed within minutes. It took them almost two months to replace one of them and the replacement was a "refurbished" unit.
